VNTBLK · expense tracker for the void
An expense tracker built like a black hole · scan fiscal receipts, run a real monthly budget, grow your savings. With an optional smart layer for AI insight, ranks and a private league.
What VNTBLK does
Everything you need for a real picture of the month · from scanning a receipt to running a budget. The core tracker is free and complete. No account, no sync, no compromise on privacy.
SUF QR scanner
Scans Serbian fiscal receipts in a single frame, parses line items, drops them straight into categories. No typing amounts.
Custom categories
Six slots you name yourself. Bills, groceries, shopping · whatever fits. Colors, icons and limits stick month after month.
Budget & income
A monthly limit per category against your income snapshot. One glance and the whole month is legible.
Savings & goals
A unified savings balance, deposits and withdrawals, multiple goals with deadlines. Pacing in real calendar months · never one number for every goal.
Commitments
Recurring bills, subscriptions and standing transfers · listed in one place, counted against the month before they hit. No surprise reds.
History & statistics
Every receipt searchable, day by day and month by month. Donut by category, Year Review on demand, trends that don't lie.
Privacy by design
Every receipt and every category lives on your phone. The backend stores aggregate signals for the league · never individual spend.
Glass-black design
Frosted dark cards, accent blue, zero noise. Built to feel calm when the economy isn't.
Bilingual
English and Serbian Latin. Switch in Settings · dates, currency and parser strings travel with the language.
The smart layer above the tracker
Void Premium is the optional, opt-in subscription that adds AI tools, faster scanning, and a competitive layer on top of everything the free tracker already does. The tracker never gets worse if you skip it · this is what waits underneath when you want more.
What's inside
Six premium features, a season-locked progression layer, and a growing achievements catalog. Most of it runs offline · the backend only sees the league. Your spend never leaves the phone.
AI Analysis
Daily, monthly and yearly insight on where your money actually goes · a paragraph in plain language, cached so it never feels noisy.
Smart budget calibration
AI tunes category limits to fit your real habits, not arbitrary defaults. Tighten, loosen, or accept · one tap each.
Receipt OCR
Snap a paper receipt · amount, merchant and items fill in for you. Same flow as QR · just with no QR.
Ranks & achievements
110+ achievements across seven tracks, nine ranks earned by lifetime XP. The catalog grows server-side · no app update needed.
Private monthly league
Compete on discipline · QR coverage, streaks, budget control · never on amount. Your numbers stay on the device. Three divisions, four-day join window.
Future cosmetics
Themes, dashboard skins, and extra rank artwork land as they ship · included for everyone already subscribed. No tiers, no upsells.
One catalog, seven tracks, lifetime XP
From inert matter to the center of a black hole
A single arc of descent. You climb by accumulating lifetime XP · once a rank is reached, it stays. No demotion on a bad month. Scroll, and fall through it.
A leaderboard scored on discipline
Never on amount. Join in the first four days of the month, compete by handle, the board locks on the last day. Promotions and relegations happen at month end.
